Solution Overview

Problem

Conventional electric candles have complex suspension mechanisms, leading to difficult assembly, high power consumption, and a lack of realism in simulating the flickering movements of a burning flame, as they do not effectively replicate the natural movements caused by surrounding air.

Innovation Solution

An electric candle design featuring a housing with a support element and actuator that allows the flame element to swing and rotate freely, using a single electromagnetic actuator to create chaotic and realistic movements, while being energy-efficient and easy to assemble, with a robust construction and enhanced realism through controlled light projection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complex suspension mechanism is used to suspend the flame element, then the flame element can be held in position, but the assembly procedure becomes difficult and requires many steps

Engineering Contradiction:
Improveflame element positioning stabilityVSAvoidsuspension mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the complex suspension mechanism entirely and replaces it with a simple support element that directly holds the flame element. The flame element is suspended freely without wires or complex attachments, extracting the unnecessary complexity while maintaining positioning stability through the support tip and engagement recess design.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a complex mechanism to hold the flame element in place, the patent inverts the approach by allowing the flame element to rest naturally on a simple support tip. The engagement recess and support tip configuration provides stability through geometric constraint rather than mechanical complexity.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If a complex suspension mechanism is used to suspend the flame element, then the flame element can be held in position, but the assembly requires a huge number of steps

Engineering Contradiction:
Improveflame element positioning stabilityVSAvoidassembly procedure simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the unnecessary suspension mechanism components and replaces them with a simple support element. The flame element assembly now requires only placing the flame element onto the support tip, reducing the assembly steps from many complex operations to a single simple action.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the support function into a dedicated support element with a support tip, separating the positioning function from the housing structure. This segmentation allows for easy assembly where the flame element simply rests on the support tip without requiring integration into complex suspension structures.

Inventive Principle:
Principle #1Segmentation

3Reliability

If conventional suspension mechanisms are used, then the flame element can be supported, but the candle has high power consumption

Engineering Contradiction:
Improveflame element supportVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The support element and engagement recess configuration allows the flame element to be supported passively through its own weight and geometric constraints. The system uses the flame element's gravity to maintain positioning without requiring active mechanical components, thereby reducing power consumption while maintaining reliable support.

Inventive Principle:
Principle #25Self-service

4Ease of manufacture

If the flame element is suspended freely without wires, then the assembly is simpler, but the flame element may unintentionally be displaced during transportation

Engineering Contradiction:
Improveassembly simplicityVSAvoidflame element position stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

Instead of using wires to prevent displacement, the patent inverts the approach by using the engagement recess and support tip geometry to create a self-locking configuration. The flame element rests on the support tip in a manner that prevents unintentional displacement without requiring additional restraining mechanisms.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The engagement recess and support tip are configured with asymmetric geometry that provides stable positioning in the intended orientation. The asymmetric design creates a stable resting position that prevents displacement during normal handling and transportation while maintaining assembly simplicity.

Inventive Principle:
Principle #4Asymmetry
